W hile for lithologic gas reservoirs in craton basins and gas reservoirs in slope zones of foreland basins, sandbodies act as the main carrier system, and hydrocarbonsm igrate both laterally and vertical2 ly with relatively long m igration distance and low delivery efficiency. Sulige gas field is of lithologic gas reser2 voirs in craton basin, itsmain carrier system is of sandbody type, with a few fault type and sandbody2fault type carrier system s. The sandbody carrier system can be subdivided into thick belt sandbody, thin belt sandbody and lenticular sandbody. The delivery capacity of carrier system varied with time. It peaked in 200 - 150 Ma during the strongest dissolution and faulting. A t the critical reservoiring period (J3 - K1 ) , the framework of car2 rier system was high in the west and north and low in the east and south, and the major carrier system consisted of sandbodies, faults and fractures. Hydrocarbons m igrated northwestward with high delivery efficiency. W hile in the post2reservoiring adjustment period ( K2 - Q) , the framework of carrier system was basically high in the east and north and low in the west and south, and the major carrier system consisted of sandbody and fractures. Hydrocarbon m igration efficiency was low and not evident.
